Pity you already ordered... Goldenstar has an 8 watt RGB plate on sale for just $2200! I've got one at the house right now; been doing some tests on it. (Still more testing to be done before I post a final review though.) The divergence is roughly similar to the OptLasers plate but the power is double. Total area on the Goldenstar plate is smaller than a sheet of notebook paper.
